In this embodiment, in the working process, when detecting that the role switching condition is triggered, the communication device may further switch one of the first bluetooth address and the second bluetooth address to be bound with another currently unbound role registration information of the AG role registration information and the HF role registration information according to the triggered role switching condition; therefore, the communication equipment can be presented to the outside as two independent AG terminals or HF terminals, the flexibility of new application provided by the Bluetooth is further improved, the Bluetooth communication equipment can be better suitable for various Bluetooth communication application scenes, and the satisfaction degree of user experience is improved.

For ease of understanding, the present embodiment is described below with reference to the role switching control method shown in fig. 4. Referring to fig. 4, the method for controlling role switching of a communication device according to this embodiment includes:

s401: the communication device detects whether the role switching condition is triggered, if so, the step goes to S402; otherwise, continuing the detection.

The communication device in this embodiment may be various devices supporting bluetooth communication, such as various mobile devices (mobile phones, IPADs), smart wearable devices (wristwatches, smart watches, bluetooth headsets), vehicle-mounted devices (e.g., vehicle-mounted terminals), or other internet of things devices. The communication device has a first bluetooth address and a second bluetooth address, wherein the first bluetooth address and the second bluetooth address are different. The communication equipment is also provided with audio gateway AG role registration information and hands-free HF role registration information, and the first Bluetooth address and the second Bluetooth address are respectively bound with the AG role registration information and the HF role registration information, so that the communication equipment is externally presented as two independent communication equipment, the communication equipment is enabled to simultaneously support the AG role and the HF role, and AG connection and/or HF connection is established with other communication equipment according to requirements, so that Bluetooth communication application is more flexible, and adaptability is better. In this embodiment, the manner in which the first bluetooth address and the second bluetooth address are respectively bound to the AG role registration information and the HF role registration information may be flexibly set, for example:

the binding mode I is as follows: the first Bluetooth address is bound with AG role registration information, and the second Bluetooth address is bound with HF role registration information;

and a second binding mode: the first bluetooth address is bound with the HF role registration information and the second bluetooth address is bound with the AG role registration information.

For the convenience of understanding, the following contents of the present embodiment are exemplified in the above binding manner one. When the second binding mode is adopted, the transformation may be performed correspondingly, which is not described in detail later.

It should be understood that the role switching condition in this embodiment can also be flexibly set according to specific requirements. For ease of understanding, the present embodiment is described below with several exemplary role switching conditions. In this example, the role switch condition may include, but is not limited to, at least one of:

receiving a role switching control instruction; the role switching control instruction can be flexibly issued by the equipment user according to requirements, and the issuing mode can also be flexibly set, for example, the role switching control instruction can be issued by touch, gesture, voice, facial expression and/or action and the like; in some application scenarios, the role switching control instruction may include indication information indicating whether to switch to the AG role or the HF role.

Detecting that two AG connections are required to be established by the communication equipment at the same time, wherein the detection mode can be determined by detecting the current communication requirement of the communication equipment in the working process; for example, when detecting that two communication devices initiate a communication connection requirement requiring the communication device to serve as an AG end to the communication device currently, or when the communication device has established bluetooth communication connection as other communication devices of the AG end currently, receiving a communication connection requirement requiring the communication device to serve as the AG end initiated by another communication device;

detecting that the communication equipment needs to establish two HF connections at the same time, wherein the detection mode can be determined by detecting the current communication requirement of the communication equipment in the working process; for example, when it is detected that two communication devices initiate a communication connection request requiring the communication device as the HF side to the communication device currently, or when the communication device has established a bluetooth communication connection as another communication device at the HF side currently, another communication device initiating a communication connection request requiring the communication device as the HF side is received.

S402: and when the role switching condition is detected to be triggered, switching one Bluetooth address of the first Bluetooth address and the second Bluetooth address into the other currently unbound role registration information of the AG role registration information and the HF role registration information according to the triggered role switching condition to bind.

For example, in combination with the first binding method, when it is determined that the communication device needs to present two AG terminals to the outside according to the triggered role switching condition, the second bluetooth address is controlled to be switched from being bound with the HF role registration information to being bound with the AG role registration information, so that the communication device presents two independent communication devices with AG functions to the outside, so that the other communication devices establish bluetooth communication connection with the communication devices.

For example, in combination with the first binding method, when it is determined that the communication device needs to be presented as two HF ends to the outside according to the triggered role switching condition, the first bluetooth address is controlled to be switched from being bound with the AG role registration information to being bound with the HF role registration information, so that the communication device is presented as two independent communication devices with HF functions to the outside, so that the other communication devices establish bluetooth communication connection with the communication devices.

It should be further understood that, in this embodiment, the manner of setting the first bluetooth address and the second bluetooth address on the communication device, and binding the AG role registration information and the HF role registration information with the first bluetooth address and the second bluetooth address respectively can also be flexibly determined according to the requirement. For ease of understanding, the present embodiment will be described below with reference to an example of setting in a bluetooth registration process performed by a specific communication apparatus.

It should be understood that the protocol stack in this embodiment may be various bluetooth protocol stacks, and may be flexibly selected according to requirements. The specific format of the bluetooth address in this embodiment can also be flexibly set according to the requirement.

In this embodiment, the registration information sent by the protocol stack includes audio gateway AG role registration information and hands-free HF role registration information; that is, the communication device in this embodiment may perform registration of the AG role and the HF role. It should be understood that, in the embodiment, when performing registration of the AG role and the HF role, the registration of the AG role and the HF role may be performed at the same time, or the registration of the AG role may be performed first, and after the registration of the AG role is completed, the registration of the HF role is performed; or the HF role registration is carried out first, and the AG role registration is carried out after the HF role registration is finished.

In this embodiment, the obtaining manner of the first bluetooth address and the second bluetooth address can be flexibly set. For ease of understanding, the present embodiment will be described below by taking several bluetooth address acquisition manners as examples.

In one example, the first bluetooth address may be a bluetooth address pre-written in the communication device, and the first bluetooth address may be stored in a bluetooth address storage file in the communication device; for example, one storage method may be binary writing into a predetermined bin file for storage. When the role is registered, the first bluetooth address can be read from the bin file. Of course, it should be understood that the first bluetooth address in this embodiment may also be dynamically generated by a preset rule when needed, and is not limited to the above-described exemplary obtaining manner.

In one example, the second bluetooth address may be obtained by, but not limited to, any one of the following three obtaining manners:

the first method is as follows: fig. 6 shows a process of acquiring the second bluetooth address, which includes:

s601: before receiving registration information sent by a protocol stack, calling a preset Bluetooth address algorithm to generate a second Bluetooth address, and storing the second Bluetooth address in a preset Bluetooth address storage file; and the second bluetooth address can be stored in a different bluetooth address storage file than the first bluetooth address, and can also be stored in the same bluetooth address storage file. For example, the second bluetooth address may be stored in a bin file stored in the first bluetooth address.

S602: and when the Bluetooth module of the communication equipment is started, reading the second Bluetooth address from the Bluetooth address storage file.

The second method comprises the following steps: and when needed, directly calling a preset Bluetooth address algorithm to generate a second Bluetooth address. This way, the second bluetooth address can be dynamically generated in real time when needed.

The third method comprises the following steps: fig. 7 shows a process of acquiring the second bluetooth address, which includes:

s701: and when the Bluetooth module of the communication equipment is started, reading the second Bluetooth address from the preset Bluetooth address storage file.

S702: judging whether the second Bluetooth address is successfully read, if so, turning to S603; otherwise, go to S604.

S703: the second bluetooth address acquisition is finished.

S704: and calling a preset Bluetooth address algorithm to generate a second Bluetooth address, and storing the generated second Bluetooth address in a Bluetooth address storage file.

It should be understood that, in this embodiment, the first bluetooth address and the second bluetooth address may be obtained simultaneously, or the first bluetooth address may be obtained first and then the second bluetooth address is obtained, or the second bluetooth address is obtained first and then the first bluetooth address is obtained, which may be flexibly obtained according to a specific application scenario.

S502: and respectively binding the first Bluetooth address and the second Bluetooth address with AG role registration information and HF role registration information.

For example, the first bluetooth address may be bound with the audio gateway AG role registration information, and the second bluetooth address may be bound with the HF role registration information; and it should be understood that, in the embodiment, the second bluetooth address may also be bound with the audio gateway AG role registration information and the first bluetooth address may also be bound with the HF role registration information when binding.

In an example of this embodiment, the first bluetooth address may be a bluetooth address pre-written in the communication device, and the first bluetooth address is stored in a bluetooth address storage file in the communication device; in this example, invoking the preset bluetooth address algorithm to generate the second bluetooth address may include:

and acquiring a first Bluetooth address, and randomly converting the value in the low-end area of the address in the first Bluetooth address to obtain a second Bluetooth address. The random switching manner in this embodiment can be flexibly adopted as long as it can be ensured that the obtained second bluetooth address is different from the first bluetooth address. In order to further improve the reliability, after the second bluetooth address is generated, whether the second bluetooth address is the same as the first bluetooth address or not can be judged, if so, the value in the low-end area of the address in the first bluetooth address is randomly transformed again to obtain the second bluetooth address, and then the second bluetooth address is compared with the first bluetooth address until the second bluetooth address is different from the first bluetooth address.

In this example, in order to further improve reliability and accuracy, it may further include detecting whether the first bluetooth address is updated, and if so, obtaining the updated first bluetooth address, and randomly transforming a value in a low-end region of an address in the updated first bluetooth address to obtain a new second bluetooth address.

Therefore, the HF role and the AG role registered by the communication equipment can be respectively bound with a mutually independent Bluetooth address, so that the communication equipment is externally presented as two independent communication equipment, the communication equipment can simultaneously support the AG role and the HF role, and AG connection and/or HF connection can be established with other communication equipment according to requirements, so that Bluetooth communication application is more flexible, adaptability is better, the communication equipment can be better suitable for various Bluetooth communication application scenes, and the satisfaction degree of user experience is improved. In the working process of the communication equipment, when the role switching condition is detected to be triggered, one of the first Bluetooth address and the second Bluetooth address can be switched to be bound with the other role registration information which is not bound currently in the AG role registration information and the HF role registration information according to the triggered role switching condition; therefore, the communication equipment can be presented to the outside as two independent AG terminals or HF terminals, the flexibility of new application provided by the Bluetooth is further improved, the Bluetooth communication equipment can be better suitable for various Bluetooth communication application scenes, and the satisfaction degree of user experience is improved.

Second embodiment

For convenience of understanding, the present embodiment is described with reference to a specific application scenario as an example on the basis of the foregoing embodiment.

In this embodiment, when the communication device writes a bluetooth address, in addition to the default configured first bluetooth address, a bluetooth address algorithm may be invoked to generate a new bluetooth address (i.e., MAC address) as the second bluetooth address, and may be written in the bin file; and optionally, the first bluetooth address and the second bluetooth address may be written into the same bin file.

Then when the bluetooth module of the communication device is started, the firmware of the bluetooth module of the communication device can directly read the first bluetooth address and the second bluetooth address from the bin file and write the first bluetooth address and the second bluetooth address into the storage space of the bluetooth module. When the communication device performs bluetooth role registration, the communication device may first perform AG role registration through a bluetooth protocol stack, and then transmit AG role registration information to a firmware of a bluetooth module of the communication device, where the firmware may bind the AG role registration information with a first bluetooth address (or, of course, a second bluetooth address); the communication device may then register the HF role via the bluetooth protocol stack and then pass the HF role registration information to the firmware of the bluetooth module of the communication device, which may bind the HF role registration information with the second bluetooth address (and of course also with the first bluetooth address). The AG function and the HF function of the communication device are thus implemented on a first bluetooth address and a second bluetooth address, respectively, which appear to the third-party device as two different communication devices, so that the first bluetooth address can always be present as a master device and the second bluetooth address can always be present as a slave device, which can flexibly establish at least one of an AG connection and an HF connection with the third-party communication device.

For ease of understanding, the present embodiment is illustrated below with an exemplary bluetooth protocol stack. Referring to fig. 8, the bluetooth protocol stack in this embodiment includes, but is not limited to, the following parts:

a PHY layer (Physical layer) for specifying a radio frequency band used for BLE, a modulation/demodulation method, a method, and the like. The PHY layer may determine the power consumption, sensitivity, and selectivity of the entire BLE chip.

The LL Layer (Link Layer) is a core of the entire BLE protocol stack, and may implement, but is not limited to, selecting which radio frequency channel to communicate, how to identify an air data packet, specifically, at which time point to send out the data packet, how to ensure integrity of data, how to receive ACK, how to retransmit, how to manage and control a Link, and the like. The LL layer is responsible for sending data out or receiving data back, and what kind of analysis is done on the data is handed over to the GAP or ATT above.

HCI (Host controller interface), which is optional, in an example, the HCI may be used in a case where 2 chips implement a BLE protocol stack, and is used to specify a communication protocol and a communication command between the two.

GAP layer (Generic access profile, Generic access specification). GAP is one of two ways to parse how LL layer payload (valid packet). GAPs simply make some specifications and definitions of LL payload, which GAPs can use to broadcast, scan, initiate connections, and so on.

L2CAP layer (logical link control and adaptation protocol), L2CAP performs a simple encapsulation on LL, LL only cares about the transmitted data itself, L2CAP shall distinguish whether it is an encrypted channel or a normal channel, and at the same time, it shall manage the connection interval.

SMP (Secure manager protocol), which is a work to be considered by SMP, is used to manage encryption and security of BLE connection, and how to ensure the security of connection without affecting user experience.

ATT (Attribute protocol), the ATT layer is used to define user commands and data of command operations, such as reading certain data or writing certain data.

GATT (Generic attribute profile), which is used to specify the data content in an attribute and apply the concept of group to classify and manage the attribute.

The present embodiment also provides an example of the structure of a bluetooth address, in which the bluetooth device address (BD _ ADDR) is a 48-bit unique identifier, and is composed of LAP (lower part of 24-bit address), UAP (upper part of 8-bit address), and NAP (16-bit meaningless address part), and its format is shown in fig. 9:

NAP and UAP are unique identification codes of manufacturers of Bluetooth devices, and are distributed to the manufacturers by SIG; LAP is self-distributed by the manufacturer. Wherein bit40 is a multicast address flag bit, and its value is 0: unicast, with a value of 1: multicast; bit41 is an address type flag bit with a value of 0: a univeral addr having a value of 1: local addr.

On the basis of the above example, the present embodiment will be described below with reference to the registration process shown in fig. 10 as an example. Please refer to fig. 10, which includes:

s1001: the bluetooth module of the communication device starts.

S1002: the bluetooth module performs registration of the AG role and the HF role.

S1003: loading the AG function and the HF function through a Bluetooth protocol stack.

S1004: and transmitting the AG role registration information and the HF role registration information to the firmware through a Bluetooth protocol stack.

S1005: judging whether the currently received registration information is AG role registration information, if so, turning to S1006; otherwise, go to S1007.

S1006: and binding the AG role registration information with the first Bluetooth address.

S1007: and binding the HF role registration information with the second Bluetooth address. Fig. 11 is a logic framework diagram corresponding to the above registration process. After address binding is completed, the rest of the search and connection may use, but is not limited to, the current protocol specifications. Therefore, the HF role and the AG role registered by the communication equipment can be respectively bound with a mutually independent Bluetooth address, so that the communication equipment is externally presented as two independent communication equipment, and the communication equipment can simultaneously support the AG role and the HF role.

In an application scenario, after the communication device completes the registration, in a working process, it is detected whether a role switching condition is triggered, for example, it is assumed that a role switching control instruction issued by a user is detected, and the role switching control instruction includes instruction information for switching to an HF role. After the communication equipment receives the role switching control instruction, the first Bluetooth address of the communication equipment is controlled to be switched to be bound with HF role registration information according to the indication information of the HF role in the role switching control instruction, and therefore the communication equipment is externally presented as two independent communication equipment with HF functions for being connected and used by external communication equipment.

In another application scenario, after the communication device completes the registration, in a working process, it detects whether a role switching condition is triggered, for example, the communication device has currently established a first bluetooth communication connection with an external second communication device, and the communication device serves as an AG end in the first bluetooth communication connection; and the communication equipment detects a Bluetooth communication connection request sent by the second communication equipment, determines that the communication equipment needs to be used as an AG end according to the request, and controls to switch the second Bluetooth address of the communication equipment into binding with AG role registration information, so that the communication equipment is externally presented as two independent communication equipment with AG function for being connected and used by external communication equipment. Therefore, the communication equipment not only can have the AG function and the HF function at the same time, but also can flexibly select and switch between the AG function and the HF function according to requirements, so that the use flexibility of the communication equipment is greatly improved, and the satisfaction degree of user experience is further improved.
